IMPROVED BED-BOTTOM.

Specification forming part of Letters Patent No. 54,281, dated May 1,1866.

To all whom it may concern:

Be it known that I, S. W. BEACH, of Niles, in the county of Berrien andState of Michigan, have invented an Improved Spring Bed- Bottom; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming a part of this specification, in which- Figure l is a plan ortop view of my in-vention. Fig. 2 is a longitudinal vertical sectiontaken on the plane of the line x x, Fig. 1. Fig. 3 is a transversevertical section taken on the plane of the line y y, Fig. 1.

Similar letters of reference indicate like parts.

My invention consists in mounting the bedbottom on levers whose lowerends are operated upon by a spring arranged transversely across thebedstead, all the parts being so constructed and arranged th at thebed-bottom will have the desired risin g-and-fallin g motion, as willbepresently described.

This spring bed-bottom can be applied to either old bedsteads-that is,those now in use-or to new ones. I have illustrated it as arranged andadapted for the former, wherein a frame, A, is employed which is to beplaced so as to be properly supported by the side and end rails of anybedstead now in use. When applied to new bedsteads this frame can bedispensed with and the bed-bottom be fastened directly within the sideand end rails of the bedstead, which will serve the purpose of the frameA.

The bed-bottom consists of the desired number of slats a, resting at theends upon crosspieces b, so as to constitute a frame, as it were, onwhich to rest the bedding. To each corner of the cross-piece b there areloosely pivoted or hinged one end, respectively, of four levers, B, theposition of said levers relatively to the slats of the bed-bottom beingat an angle of about thirty degrees. Upon the lower end of these leversB a metallic spring, C, is secured by bolting it at each side to therespective levers, as shown clearlyin'Figs. 1 and 2. This spring isarranged transversely acro'ss the bedstead, and should be near thecenter lon gitudinally of the bedstead.

D is a cross-piece, extending from side to side of the frame A, or ofthe bedstead if the frame be dispensed with and E E are two crosslrods,also extending across the frame A. The cross-beam D is arranged directlyunder the spring C, and to it the said spring is bolted at about itscenter, thus throwing the effective parts of the spring at each endthereof. The levers B, near their lower ends, rest upon the cross-rods EE, which constitute their fulcrumpoints, leaving the longer ends of thearms of the levers above the fulcrum-points.

From the above description it will be seen that on depressing thebed-bottom a b the lower ends of the levers B will be caused tov rise,and thus the spring C will be brought into eIiect-ive operation, as canbe readily understood.

This invention produces alight, easy, and

durable bed-bottom, and one that can be applied with but comparativelylittle expense to either an old or new bedstead.

What I claim as new, and desire to secure by Letters Patent, is

1. The levers B B, in combination with the bed-bottom a b and spring G,substantially as speciied.

2. So mounting a bed-bottom that the same will receive its necessaryspringing motion from a single spring, G, arranged so as to operatesubstantially as specified.
